Molecular role of ethylene in fruit r​ipening of Ziziphus jujube Mill.

ABSTRACT: The fruit of Chinese jujube (Ziziphus jujube) is widely consumed by human beings due to its high proteins, vitamins, and mineral nutrients. The harvest time of Chinese jujube fruit determines its quality, while ethylene plays a pivotal role in fruit ripening. Nevertheless, the relationship between ethylene biosynthesis/signal transduction and fruit ripening of Chinese jujube is still elusive. Here, the Chinese jujube fruit ripening with its fruit peel color change from cyan to dark red at seven different ripening stages (stage I-VII) and expression levels of genes related to ethylene synthesis and signal transduction were determined. Results showed that expression levels of ZjACO1-3, ZjETR2, ZjERF1, and ZjERF4 were increasingly upregulated, whereas the expression level
